13 axk(7/8) socket and header are mated socket header 0.3mm 1.8mm pcb narrow-pitch connectors p4 fpc reinforcing plate before mating ideal for fpc-to-pcb connections after mating the simple lock mechanism ensures that the connector clicks into position when it is inserted for reliable single-action insertion on the pcb. a stacking height of 1.8mm including the fpc area has been achieved. this enables the number of pins to be doubled white the size remains the same as that for existing fpc connectors. this, in turn, contributes to making products and equipment more compact. features 1. a 0.4 mm pitch and stacking height of 1.5 mm allow for extra compactness and helps design lighter, thinner, shorter, and smaller devices. 2. high impact-resistant construction. 1) adoption of bellows-type contacts structure. 2) it is constructed with impact dispersion keys inside the body to disperse shocks when dropped. a high level of shock resistance is ensured by dispersing impact over the four locations where the socket indenta- tions and header protrusions are mated together. 3. construction makes designing devices easier. 1) the lower connector surface construc- tion prevents contact and shorts between the pcb and metal terminals. this enables freedom in pattern wiring, help- ing to make pcb s smaller. 2) guides are provided to take up any position shift and facilitate insertion. 3) the connector has a simple lock mechanism. 4. design makes ef?ient mounting. features a terminal ?tness of 0.08 mm, construction resistant to creeping ?x, and design that facilitates visual inspec- tion of the soldered part. applications ?cellular phones ?dvc ?compact portable devices since the contact is formed by bending thin plate, it has a spring- like quality. this construction helps make it resistant to dropping and twisting. the roll surfaces are in contact with each other, providing high contact reliability. impact dispersion key socket header connector bottom: create any thru-hole pattern wiring. insertion guide socket side contact header side contact simple lock mechanism narrow-pitch connectors for pc boards narrow pitch (0.4mm) connectors p4 series product types notes) 1. regarding ordering units: during production, please make orders in 1-reel units. samples for mounting con rmation: please consult us.
